Mike, Have a number of systems, with similar symptoms happening from time to
time on one system or another.  Used to do resets to recover the tape drive,
but recently we've found a simpler method -- remove tape, insert a
*different* tape. Don't know why, but *changing* the tape often causes the
tape drive to reset itself (may take a minute or two for the drive to
recover ... watch the light and track the vibrations). We then find that if
we change the tape back, we often have to wait 5 minutes or more for the
original tape to rewind, and then everything is operational.

But every so often we find that the original tape has simply gone bad. Drive
resets and works OK with 2nd (or very rarely, 3rd) tape in it, but first
tape always causes tape to act as if hung. Toss tape (or send it back to
manufacturer for replacement).

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
